HOSE-COUPLIN G AND HOSE-FASTENEB.

Specification of Letters Patent. Patented Sept. 17, 1912. Application iled June 14, 1909. Seal No. 502,157.

To all lwhom it may] concern -l Be it knownthat I, WILLIAM E. PATRICK, a citizen of the United States, residing at Newport, in the county of Newport and State of Rhode Island, have invented a new and useful Hose-Couplin and Hose-Fastener, of which the followlng is a specification.

This invention relates to improvements in hose couplings, and the object is to provide u simple and improved coupling-device by means of which a hose may be quickly and readily coupled or uncoupled and when coupled will be securely held without leaking, together with means lfor securing the hose to the coupler-members.

In the accompanying drawings z-Figure 1 is a longitudinal sectional view of my improved hose-coupling, t-he two coupler-members being shown, connected, and also the l hose-clamping device; Fig. 2, a side and an end view of one of the coupler-members; Fig. 3,' a slde and end vlewvof the other coupler-member; Fig. 4, a side and an end Viewv cf the locking-member of the coupling; Fig. 5, a plan and an edge view of one of the springmembers carried by the lockingmem ber; ig. 6, a longitudinal sectional view and an end view of the one member ofthe hose-clamping device, of which latter there are two; Fig. 7, a longitudinal sectional view and an end view of the other member of the hose-clamping-device; Fi 8, illustrates the packing ring in side and ace views. Y

- Referring now more particularly to the accompanyi ng drawing, the letter A designates the male-member of the coupling having the shank or tail-portion a which is grooved or roughened and is inserted in the end of one ofthe sections of hose. Said male-member is formed at the forward end of the shank with a threaded shoulder a1, a bearing a for the locking-sleeve to rotate on, and an annular shoulder a. Said member A is also formed on the opposite side of shoulder a to the bearing a2 with an annular shoulder or seat a4 and forward of that with a ta ered plug a5. A passage extends longitudinally through the entire coupler-memberas shown by dotted lines, Fig. The female-member of the coupler is designated by the letter B and consists of .a

shank bsimilar to the shank a to fit intothe end of the other hose-section.l At the for-A ward end of theshank is a threaded shoulder b1 and an enlarged body bhaving a tapered-bore b to receive the tapered plug C designates the locking-sleeve having an annular seat c1 of a size to receive the body b2 and bearing a2 and having at its inne-1` end a vshoulder to abut shoulder aofV t-he malemember. Said locking-sleeve "is formed at lits outer end on opposlte sides of its center with inwardly-extending straight-slots et terminating in inclined slots -05 which are disposed oppositely to each other. The two slots c and c5 form bayonet-slots one portion of which is inclined. At its. inner end said sleeve is provided about its exterior with a rflange c2 by means of which it may be rot-ated, which angemay be knurled. Secured at one end by screws in slots o 'formed in the knurled flange c2 on opposite sides 'of the center of the sleeve, are springmembers D having their outer ends d2 bent outwardlyslightly so that they may be lifted out of engagement with the `rojec tions or lugs b". The free ends-o these springs extend across theA inclined slots c5 at one side of slots c* in the path of s'aid projections.

The o eration of my coupling as above described) is as follows The male-member .A of the coupling is inserted in the lockingsleeve. Then the female-member B with the packing-ring in place is pushed into the locking-sleeve, over the taper-plug a5 of the male-member until the packing-ring comes in contact with the shoulder a, the lockingprojections b* passing through the slots c* until the slots c are reached. The locking f sleeve is. thenA rotated by means of the knurled flange e until the projectionscome in contact with the inclined walls of the slots c, and as the rotation of the sleeve is continued the springs D come in contact with the inclined or cam sides of the projections or lugs which eiiect the raising of said springs` until said lugs pass. The springs then return to normal position and are engaged by the notches b of said lugs, thus -ing e at oneend preventing rotation of't-he sleeve in a r'everse direction untll the sprm are dlsen- .gaged manually from the notc es. As. the

sleeve is rotated, the coaction of the projections or lugs with the inclinedwalls of the slots c", forces the coupler members together, making a tight joint. at the packingfring AGr and holding said members securely.l

i lshoulder of coupler-member B.V vThe body at f1. to take'the threads of the sleeve.

of the sleeve is exteriorly screw-threaded at e* and is split to form yielding clamping sections or jaws el, which are compressed by a nut F which is interiorly screw-threargd nut at one 'end on its interior is formed a with a tapered portion f? which when the v nut is Vscrewecl-onthe sleeve comes in contact with the ltapered exterior portion e5 at Y one end of the sleeve and forces the lips e2 formed on the inner sides of the clamping jaws into the hose and compresses the latter into the shank of the coupler-member. Both the sleeve and nut are formed with holes y for a Spanner wrench. A Having thus fully described my invenu tion what I claim asrnew and desire to secure by Letters Patent of theUnited States, 1s:- A

1. A hose coupling comprising a female section having a ,bayonet slot in one' end thereof, a male section provided with a laterally extending lug member adapted to engage in the bayonet slot and a spring member disposed across said slot and ex.A tending longitudinally of said female sec` tion, said lug member and said spring member coacting to lock provided with a cam surface.

the sections in assem- ,bled relation, one of said members being 2. A hosegcoupling comprising abutting members,l a pluralityv of pins on one member having cam surr'acesV on one side and notches on the other side, the other of said members having bayonet slots for said pins, and outwardly ylelding members extendingacross said bayonetslots and adapted to be moved` "out ofthe path of the pins when the abut" ting members are given -relative rotation in` one direction, by engagemento'f the cam.

surfaces of the pins therewith, and on rota- 55 tion in the opposite direction to be engaged by the notches of said pins. v

3. A hose coupling comprising a malemember, a female member, and a sleeve for; inclu-sing the abutting ends of said members and having bayonet slots formed therein, means for maintaining saids'leeve on one of said members, pins on the other of said members adapted to work in said bayonet slots to draw themembers together, and outwardly yielding members extending across said slots, said pins having entering sides cani-shaped and the opposite sides notched said. yielding members adapted to be moved out of the path of the pins when the abu 570' ting members are given relative rotationin one direction, by engagement of the vpins therewith and on rotation'in the opposite direction tobe engaged by the notches of the pins. Y Y 4. A hose coupling comprising abutting f members, a plurality of pins on one member having cam surfaces on one side, the other y of said members having bayonet `slots for said pins, extending substantially lengthwise ofl the aibutting members and across. said bayonet. s ots.
